Un dispositif de balayage optique (24) balaie l'étiquette d'un article positionné sur l'organe mobile de support (29) et produit un premier groupe de signaux de données identifiant l'article, les faisceaux lumineux de balayage traversant une partie translucide (39, 46) de l'organe mobile de support (29). Celui-ci est agencé de manière à se déplacer vers le bas lorsqu'un article y est posé, et des organes générateurs de signaux en prise avec l'organe mobile de support (29) produisent un deuxième groupe de signaux de données représentant le poids de l'article. Les premier et deuxième groupes de signaux de données sont appliqués à un terminal de données qui produit un troisième groupe de signaux de données représentant le prix de l'article identifié.
